The blending of different ore types is a common practice to provide a consistent feed to a process in terms of uniform hardness or assay. When several different ore deposits of varying grindabilities are blended prior to closed circuit grinding, the work index of the ore is not an average or even a weighted average of the work indices of the components.

Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
electrowinning circuit is designed or why the numbers of hodes per cells are different for the copper production rate of 20 and 40 ktpa. These questions relate much more to the determination of the number and dimensions of equipment. The purpose of this publiion is to gives the procedure of copper electrowinning circuit equipment sizing and
TankCell flotation units are built to last. For instance, Outotec rotors and stators have proven to be the most wearresistant available. The wide range of available cell sizes enables a compact, economical, and efficient plant design without risk of short circuiting, even for today''s hightonnage operations.

Innovations: How Hydrometallurgy and the SX/EW Process
The copperbearing aqueous phase is advanced to the electrowinning (EW) stage of the process while the barren organic phase is returned to the extraction stage of the process. In the electrowinning stage of the process the copper is reduced electrochemically from copper sulfate in solution to a metallic copper hode. In China, for example
The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The goldrich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto hodes of steel wool. The loaded steel wool is pretreated by calcination before it is mixed with ﬂuxes and melted.
